Hardware-in-loop real-time simulation of electrical vehicle using multi-simulation platform based on data fusion approach

Abstract

A hardware-in-loop real-time multi-simulation platform system is established based on data fusion approach, and the vehicle closed-loop control system is obtained based on “driver–central controller–motor drive system–vehicle dynamics,” on which the control strategy of wheel-motor-driven multi-axle vehicle is verified. Data among the platform are transformed based on FlexRay bus. A simulation experiment of electrical vehicle dynamic performance is tested by real driver in real time to analyze whether vehicle dynamic performance is performed based on the multi-platform. The results indicate that the hardware-in-loop real-time simulation system can effectively verify the reliability of control strategy, and the data fusion of multi-simulation-platform works well.
